The influence of two anecic earthworm species, Lumbricus terrestris and Aporrectodea giardi, on the soil adjacent to their burrows was studied in the laboratory. The morphological, physical and biochemical characteristics of the burrow walls were compared with those of casts and surrounding soil by scanning electron microscopy and measurement of water stable aggregation (WSA), enzymatic activities and elemental content (C and N).
